Description
Overview:
This Genuine JAP piston assembly (OEM No. SSA15) is a standard-size replacement for J.A.P.'s Model 80 JS8 single-cylinder engines. Manufactured in durable aluminium alloy to manage heat and reduce reciprocating mass, it restores compression and smooth running when overhauling a tired unit. The standard bore is 46 mm (1.81 in), matching the original factory size for straightforward fitment without machining. Suitable for small plant and vintage machinery powered by JAP engines, such as compactors, generators, pumps and similar equipment, it helps return reliable starting and steady power output. Supplied as unused old stock, it may show light age-related tarnish or storage marks, but remains a dependable OEM-grade component for maintenance, repairs and period-correct restorations of Model 80 JS8 engines.
Key Features:
- Genuine JAP component with OEM reference SSA15 for assured compatibility and performance
- Standard bore 46 mm (1.81 in) to match factory cylinder size and simplify replacement

Ideal where original specification, long service life and consistent performance are required without oversize reboring.
